Learn lessons, pave the way for future work, and take fewer detours. Most college students will engage in social work as soon as they graduate. Although the university is a small society, it is quite different from the real society, so many people will not adapt to it when they enter the society for the first time. If you can work part-time in a university, you can get in touch with the real society in advance. This is good for college students, so that people will not feel too uncomfortable when looking for a job.
